1 Units and Vectors: Tools for Physics. 1 .. the equations we derive in working these problems really needs to re–take some math courses! Vectors - Motion and Forces in Two Dimensions - Lesson 1 - Vectors: Fundamentals Let's test your understanding with the following two practice problems. Vectors and Projectiles: Problem Set. Problem 1: Coach Sweeney walks 26 yards to the north along the sideline, pauses, and walks 12 yards back to the south.

The mathematics of the above problem is no more difficult than dividing or multiplying two numerical quantities by each other. The mathematics is easy!
Vectors and Direction
The difficulty of the problem is conceptual in nature; the difficulty lies in deciding which numbers to use in vectors physics problems equations.
That decision emerges from one's conceptual understanding or unfortunately, one's misunderstanding of the complex motion that is occurring. The motion of the riverboat can be divided into two simultaneous parts - a motion in the direction straight across the river and a motion in the downstream direction.
These two parts or components of the motion occur simultaneously for the same time duration which was 20 seconds in the above problem. The decision as to which velocity value or distance value to use in the equation must be consistent with the diagram above.
Vectors and Direction
The boat's motor is what carries the boat across the river the Distance A; vectors physics problems so any calculation involving the Distance A must involve the speed value labeled as Speed A the boat speed relative to the water.
Similarly, it is the current of the river that carries the boat downstream for the Distance B; and so any calculation involving the Distance B must involve the speed value labeled as Speed B the river speed. Since your answers were determined using a scaled vector diagram, small errors in vectors physics problems measurement of the direction and magnitude of any one of the vectors may lead to small differences between your answers and the correct ones which are shown here.
The arrow is drawn a precise length in accordance with a chosen scale. For example, the diagram at the right shows a vector with a magnitude of 20 miles. Similarly, a mile displacement vector is represented by a 5-cm long vector arrow.

And finally, an mile displacement vector is represented by a 3. See the examples shown below.

In conclusion, vectors can be represented by use of a scaled vector diagram. On such a diagram, a vector arrow is drawn to represent the vector.
The arrow has an obvious vectors physics problems and arrowhead.
vectors physics problems The magnitude of a vector is represented by the length of the arrow. The arrow points in the precise direction. Directions are described by the use of some convention.
Vector Resolution & Components
Also vectors physics problems — subtract them. How does one add vectors at right angles. Reasonably simple — use pythagorean theorem and tangent. Brutally simple — resolve them into components. Don't let the vectors make you work harder.
Starting at home base, these 18 displacement vectors could be added together in consecutive fashion to determine the result of adding the set of 18 directions. Perhaps the first vector is measured 5 cm, East. Where this measurement ended, the vectors physics problems measurement would begin.

The process would be repeated for all 18 directions. Each time one measurement ended, the next measurement would begin. In essence, you vectors physics problems be using the head-to-tail method of vector addition.
